Nvidia said on Thursday its products have no "backdoors" that would allow remote access or control after China raised concerns over potential security risks in the firm's H20 artificial intelligence chip.

China's cyberspace regulators have summoned Nvidia over security concerns about its H20 chips. They claim the chips can be tracked and turned off remotely.

China state media is calling for Nvidia Corp. to prove that its H20 chip is secure, saying it can’t allow flawed chips into the country.
